I thought this movie had a good plot and was generally entertaining. The premise that planet earth would have to go to another planet to find natural resources because it had drained its own seemed plausible as well. This movie quite possibly everything: interesting storyline, intense action scenes, and it even had me rooting for the natives at the end of the movie. The one negative I see in this movie is the 3D presentation. Too many times the picture seemed blurry, and I did not feel the characters and background jumped out at me enough the way I expect 3D to. Other than that, I thought it was a really good movie.
